2018-07-22	blk-rq-qos: make depth comparisons unsigned	Josef Bacik	1	-4/+4
	With the change to use UINT_MAX I broke the depth check as any value of inflight (ie 0) would be less than (int)UINT_MAX. Fix this by changing everything to unsigned int to match the depth. Signed-off-by: Josef Bacik <josef@toxicpanda.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2018-07-09	rq-qos: introduce dio_bio callback	Josef Bacik	1	-0/+10
	wbt cares only about request completion time, but controllers may need information that is on the bio itself, so add a done_bio callback for rq-qos so things like blk-iolatency can use it to have the bio when it completes.

2018-07-09	block: remove external dependency on wbt_flags	Josef Bacik	1	-9/+15
	We don't really need to save this stuff in the core block code, we can just pass the bio back into the helpers later on to derive the same flags and update the rq->wbt_flags appropriately. Signed-off-by: Josef Bacik <jbacik@fb.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2018-07-09	blk-rq-qos: refactor out common elements of blk-wbt	Josef Bacik	1	-0/+178
	blkcg-qos is going to do essentially what wbt does, only on a cgroup basis. Break out the common code that will be shared between blkcg-qos and wbt into blk-rq-qos.* so they can both utilize the same infrastructure.
